sa-learn doesn't remember messages it's already learned from

[Russell Jones]

I am running a global bayes database. The file permissions for the 
database is 0666. For some reason I just realized that sa-learn is not 
remembering the messages it's already learned from. I've checked the 
bayes file permissions and everything else I could think of, but if you 
run sa-learn, wait for it to finish, and then run it again it learns off 
of the same messages. (IE, learned 5 tokens from 5 messages. This will 
show everytime you run sa-learn). Nothing has changed from my 
configuration that should have caused this.

I am running SpamAssassin 3.2.5, Perl 5.8.8. There are no errors shown 
when sa-learn finishes. Any ideas what I could look at as the cause for 
this?

Thanks!
